DATA SHEET LM10D01_17 Issue 17, 20th April 2023 LM10 Incremental Magnetic Encoder UNIQUE REFERENCE MARK The LM10 is a non-contact high-speed magnetic encoder designed for linear or rotary motion sensing in harsh environments. It features a compact readhead that rides at up to 1.0 mm from the self-adhesive magnetic scale or ring. Simple to install, the LM10 features a set-up LED and wide installation tolerances. The encoder comes in digital or analogue output variants and offers a range of customer selectable resolutions from 0.244 μm to 250 μm. WEAR-FREE MEASURING PRINCIPLE Customer selectable resolutions High speed operation Excellent dirt immunity to IP68 Linear or rotary position sensing Unique bidirectional reference mark INDUSTRIAL AUTOMATION ASSEMBLY LINES Non-contact and wear-free measuring principle CE compliant, including RoHS Highly resistant to shock, vibration and pressure LINEAR MOTOR PRINTING TECHNOLOGY

General information Engineered for extreme service, the solid-state LM10 linear encoders operate from –10 °C to +80 °C, have water-proof sealing to IP68 and are highly resistant to shock, vibration and pressure. The robust magnetic scale and ring are also resistant to various chemicals commonly found in industry. The non-contact, frictionless design eliminates wear and reduces hysteresis. Choose your LM10 system The robust LM10 readhead is compatible with the RLS MS10 incremental scale as well as the RLS axial and radial rings. You can select the length of the MS scale up to 150 m. There is...

Storage and handling All data given below refer to the readhead only. Complete systems with magnetic scale or ring may have other limitations. For more information, see the MSD01, MR01D01 or MR02D02 data sheet at RLS Media center. Storage temperature Operating temperature Readhead is ESD sensitive - handle with care. Do not touch electronic circuit, wires or sensor area without proper ESD protection or outside of ESD controlled environment. This encoder system is a high performance metrology product and must be handled carefully. The use of industrial tools during installation or exposure...

Set-up time is the time needed for the encoder readhead to start reading the position information after power-on (see diagram 1). Interpolation conversion time is the time needed for the encoder readhead to convert the position information into an output signal. Transition time is the time it takes the encoder readhead to switch from an alarm state to a valid output signal (see diagram 2).
